To all whom it may concern:

Be it known that I, JAMES N. VANDE- GRIFT, of Syracuse, in the county ofOnondaga and State of New York, have invented a certain new and usefulCar-W'Vheel, of which the following is a specification.

This invention has for its object the pro duct-ion of a particularlysimple and efficient car wheel and it consists in the combinations andconstructions hereinafter set forth and claimed.

In describing this invent-ion reference is had to the accompanyingdrawing which is a vertical sectional view of my car wheel, thecontiguous portion of the axle being also shown.

This car wheel comprises a hub for encircling the axle, a web mounted onthe hub and separable therefrom, a tread carried by the web, a drivinggear mounted on the hub, and means for securing the driving gear and webto the hub.

1 is the axle, said axle preferably having a sleeve 2 thereon; the innerend of the sleeve abutting against a shoulder 3 on the axle.

4: is the hub of the wheel, the hub 4 encircling the axle 1 and thesleeve 2 thereon, and constituting a journal box or holder forantifriction bearings.

5 is the web of the wheel, such web being separable from the hub.

6 is the flanged tread carried by the web; and 7 is the driving gearmounted on the hub and detachable therefrom.

The hub 4: is formed with a circumferential peripheral flange 8 and theweb 5 and gear 7 are mounted on opposite sides of such flange and aresecured to the hub in order to rotate therewith by fastening meansextending transversely through such web 5, flange 8 and gear 7. As hereshown the flange 8 is formed with series of bosses 9 projecting fromopposite sides thereof toward the web 5 and gear 7 respectively, andabutting against opposing faces thereof, and bolts 10 are passedtransversely through the gear 7, flange 8 and bosses 9 thereof, and theweb 5.

Suitable antifriction and thrust bearings are shown as interposedbet-ween my improved car wheel and the axle 1, but these bearings arenot described, as they form no part of the present invention.

What I claim is:

1. The combination with an axle, of a wheel comprising a hub encirclingthe axle and formed with a peripheral flange, a web mounted on the hubon one side of the flange and separable therefrom, a tread supported bythe web, and a driving gear mounted on the hub on the other side of theflange, substantially as and for the purpose specified.

2. The combination with an axle, of a wheel comprising a hub inclosingthe axle and formed with a peripheral flange, a web mounted on the hubon one side of the flange and separable therefrom, a tread supported bythe web, a driving gear mounted on the hub on the other side of theflange, and fastening means extending transversely through the drivinggear, flange and web, substantially as and for the purpose described.

3. The combination with an axle, of a wheel comprising a hub inclosingthe axle and formed with a peripheral flange, a web mounted on the hubon one side of the flange and separable therefrom, a tread supported bythe web, the flange having two series of bosses projecting in oppositedirect-ions therefrom, one series of bosses coacting with the web, adriving gear mounted on the hub on the other side of the flange andabutting against the ends of the other series of bosses, and fasteningmeans extending transversely through the driving gear, the flange andbosses thereof and the web of the wheel, js lulglstantially as and forthe purpose speci- In testimony whereof, I have hereunto signed my namein the presence of two attesting witnesses, at Syracuse, in the countyof Onondaga, in the State of New York, this 6th day of December, 1910.
